The installation went fine until the time the computer restarted? & Lo!!! I got this queer BOOTMGR error!!!!!!!!!!!!
After Googling here and there for the solution... I eventually arrived at one. Follow the steps below:
1. First go to your BIOS (at the time of restart) by pressing F2 and change your Boot Priority to CD\DVD.
2. Save and Exit and the computer will restart. An option like "Press any key to boot from CD will be displayed on your screen.... " Press any key.... After sometime the windows Installation Menu will appear.. Select your option (which is not important... I mean any option can be selected..") and click next...
3. Click 'Repair my Computer'
At the prompt to select your OS installation, click the button that says 'Load Drivers'. This should bring up a explorer-style drive browser.
Then just right-click on the drive you tried to compress, and deselect 'Compress this Drive', which should still be ticked on. Hit apply, and apply to subfolders/files. Usually it must be the C:\ drive.. You can go to your C:\ drive by clicking on My Computer or Computer... Once the C:\ drive is displayed.. Right click on it.. Select Properties.. and then Uncheck "Compress this drive to save disk space" & Reboot.
Your Problem should resolve!!!!
